Dates: February 1-21
The group plans to test the two-way communication between the website and the device microchip. We will be using an ESP32 microchip which has built-in wifi and Bluetooth capabilities. The website and device will be connected by a Firebase Realtime database. We will test data flow from the website to the device to represent dispensing commands and the device to the website to represent sensor readings and counts.
Dates: January 17-30
The alpha prototyping process highlighted components that could be changed for better performance. The group is currently researching servo motors that rotate 360 degrees and move to specified angles with precision. The group will also purchase a linear actuator with a larger range of motion. These components will be ordered as soon as possible, and incorporated into the prototype for testing at the beginning of Phase 4.

In Phase 3, multiple components were prototyped using 3D printing. For the next phase, the team plans to experiment with other materials for the rotating plates, including cardboard and plastic. These materials can be cut quickly and accurately, which would be useful for any design pivots. The material spreading that impacted the tolerances of the first prototype would also be avoided by using the laser cutter instead. The team plans to follow up with the MakerSpace employees at the beginning of Phase 4 for guidance.
The team plans to perform testing on the virtual model created in Phase 3. The first simulations performed will include a kinematic motion analysis and drop test. The team also plans to utilize event based motion analysis. This simulation will include the incorporation of sensors to represent the linear actuator and servo motors. The simulations will help identify any design concerns that should be addressed in the prototyping process.
